Java libraries for Gaussian splats.

• jsplat - The core library, with interfaces for splats and readers and writers
• Reader/writer libraries:
  • jsplat-io-gsplat - gsplat format
  • jsplat-io-ply - PLY files
  • jsplat-io-spz - SPZ format
  • jsplat-io-gltf - glTF with KHR_gaussian_splatting
  • jsplat-io-gltf-spz - glTF with KHR_spz_gaussian_splatting_compression_spz_2
  • jsplat-io-sog - SOG Format, with a basic reader and an experimental (and slow) writer.

A basic viewer implementation can be found in jsplat-viewer, with the actual implementation based on LWJGL in jsplat-viewer-lwjgl.

A basic application that brings together all JSplat libraries can be found in jsplat-app.

The viewer and application are experimental. In order to view existing splat files, I recommend babylon.js: It supports most of the formats that are commonly used, and can conveniently display them via drag-and-drop.

An example

// Create an input stream for the PLY data
InputStream is = new FileInputStream("./data/unitCube-ascii.ply");

// Create a PLY reader, and read the splats
SplatListReader r = new PlySplatReader();
List<MutableSplat> splats = r.readList(is);

// Create an output stream for the SPZ data
OutputStream os = new FileOutputStream("./data/unitCube-output.spz");

// Create an SPZ writer, and write the splats
SplatListWriter w = new SpzSplatWriter();
w.writeList(splats, os);

Further examples can be found in the examples project.
